Definitions

  • the present invention initially relates to a method for producing a plastic container according to the preambles of claims 1 and 5. Furthermore, the invention also relates to a plastic container.
  • Plastic container of the type mentioned in particular have a container body, which in turn has a container bottom and a container wall, wherein the container wall forms the side wall of the container.
  • the container wall may consist of one or more container wall segments. If only one container wall segment is present, the container or the container body has, for example, a round, oval or elliptical contour. If the container has two or more container wall segments, they usually adjoin one another; wherein in each case a container edge is formed in the region of the adjoining. Even if a plurality of container wall segments are provided with intermediate container edges, the plastic container can preferably be made in one piece.
  • plastic containers are produced by being centrally filled via an injection point - from the bottom of the container.
  • an injection point - When reducing wall thickness but increases the pressure requirement in the injection mold. Thus, the injected plastic is more heavily loaded to possibly damaged.
  • the flow path lengths must be shortened. This can be achieved by a Mehrfachanspritzung at appropriate locations.
  • Such a solution is for example in the FR 2 789 343 B described.
  • a plastic container of the type mentioned is produced by means of an injection molding process, wherein the gating takes place respectively on the side surfaces, that is on the surfaces of the container wall segments, and on the surface of the container bottom. The gating takes place in each case surface centered.
  • this known solution has a number of disadvantages. In particular, there is a risk of incidence or distortions in the area of the injection points on the surfaces, since in the area of the injection points they are so-called hot-spot areas, caused by the injection of the hot material and the construction-related material accumulation in the gate to gate transition container wall. These bumps on the side walls hinder the subsequent attachment of stickers or the printing of the areas. Also "In Mold Labels" are very inadequate to realize. The visual appearance is inferior.
  • the present invention has the object, a method of the type mentioned in such a way that the aforementioned disadvantages can be avoided. Furthermore, a correspondingly improved plastic container should also be provided.
  • the inventive idea of the present invention consists in the fact that no longer centrally or centrally sprayed on the side surfaces of the plastic container, but rather on the edges of the plastic container or in the region of the edges of the plastic container.

  • the method is inventively characterized in that the gating on at least a container side wall segment of the plastic container in the region of at least one edge of the container takes place.
  • a method for producing a plastic container in particular a refuse container, which represents a combination of the two methods described above, wherein the gating on at least one container edge of the plastic container and on at least one container side wall segment of the plastic container in the area at least a container edge takes place.
  • the inventive methods are designed for producing a plastic container.
  • the invention is not limited to certain types of plastic containers.
  • a refuse container can be produced by means of the method according to the invention.
  • such a plastic container has a container wall, wherein the container wall forms the side wall of the container, which limits the container to the sides.
  • a plastic container has a container bottom, which is to be distinguished from the container side wall, and which limits the plastic container at the bottom.
  • the container bottom and the container side wall form the container body.
  • the container side wall can consist of two or more container side wall segments, which adjoin one another. In the area of the adjoining, a container edge is then provided or formed in each case, or else the adjoining itself is designed as a container edge.
  • a container edge within the meaning of the present patent application is thus constantly between two adjoining container sidewall segments. In particular, such container edges are rounded container edges.

  • the spray process is basically characterized in that the individual components of the plastic container are molded. These components of the container are, in particular, the container bottom and the container sidewall, which consists of at least two container sidewall segments.
  • the individual components of the container are molded by means of the spray process. This means in particular that the material is injected into a tool, for example into a cavity of a tool which has the contour or at least approximately the contour of the plastic container to be produced. whereby the individual components of the plastic container arise. A preferred example of how this can be done will be described in greater detail below.

  • Such an embodiment of the method according to the three aforementioned aspects of the invention has a number of advantages.
  • An advantage in the gating on the container edges and / or in the region of the container edges, that is in corner positions, is that in contrast to the central gating on the surfaces, as is known from the prior art, no risk of incidence, recoveries or constrictions by so-called hot spot areas of the surface in the Anspritz Scheme more is given because the corners are much more stable.
